Complete Japanese system of filtration and improvement of the water quality imported since 2008 and marketed since more than 30 years in Japan.

Lifespan + 200 000 litres, thanks to a system of exclusive weekly retro-cleaning, i.e. approximately 10 years of use.

The Naturalizer is made of stainless steel with natural materials for filtration (rocks, coconut charcoal). System adopted by the Hippocrates Health Institute in the USA and installed in several hospitals and clinics in Japan.

The main advantage of this filter lies in its retro-cleaning system which eliminates the need to purchase replacement cartridges. Biovie has decided to buy directly from the Japanese manufacturer to offer this model at the best price.


The principle of the Naturalizer water filter is the circulation of water through different layers, thus reproducing the natural course of water in nature. It is probably one of the only water filters on the market to use only natural materials.

Two phases follow: an actual filtration phase and a phase of improvement of the physical and subtle qualities of the water, or dynamization. The majority of systems only offer filtration or dynamization, rarely both.

The rocks used are volcanic rocks whose properties were officially recognized by Japanese health authorities in 1990 and 1995 (still in force).

The filter is made of six different natural materials arranged in nine successive layers.

Components of the filter NATURALIZER KIRAMEKI

volcanic sand
This sand of volcanic origin has been repolished to increase its contact surface and its porosity. Its main function is to form a barrier to tiny solids in suspension, such as rust particles or sediments for example. In synergy with charcoal, it also allows the adsorption of heavy metals, pesticides, PCBs and MTBE. It also prevents contamination by E.coli, Cryptosporidians, or Giardia parasites and bacteria down to a size of 0.5 microns.

Activated charcoal
This activated charcoal has been made from the finest quality coconut fibers. This charcoal reduces a very broad spectrum of chemical contaminants to an undetectable level. Charcoal notably retains chlorine, chloramines, trihalomethanes (THMs), pesticides, volatile organic compounds (VOCs), organic matter, as well as matter filtered in synergy with volcanic sand.

Magnetite is a naturally magnetic rock. In the filter, it is sandwiched between two powerful ceramic magnets. This patented system generates an intense magnetic field (of the order of 4000 Gauss) which cleans the energy structure of the water, eliminating the electromagnetic signatures of the contaminants filtered by the two upper layers.

The water is then restructured in the form of micro-clusters, its surface tension decreases, which significantly improves its bioavailability for the cells of the body and thus its hydration capacities. This effect also allows the water to carry more substances into solution by preventing their precipitation (particularly limestone).

Tachyo volcanic rock
This rock of volcanic origin produces in the presence of water an oxidation-reduction reaction which eliminates micro-organisms, prevents the development of bacteria, fungi, algae in the filtered water as well as in the filter itself.

It was officially recognized by the Kitazato Health University in Tokyo on December 15, 1990 as having the properties of a "natural disinfectant".

Bakuhan volcanic rock
This rock of volcanic origin contributes to the reduction of the surface tension of the water, will stabilize the water towards a slightly alkaline value thanks to its buffer effect, increases the quantity of oxygen dissolved in the water. It also allows the adsorption and degradation of undesirable substances and participates in the creation of water having the properties of mountain spring water with the addition of minerals in small quantities (silica, potassium, magnesium, calcium ).

This rock also has anti-bacterial and anti-fungal properties which, in synergy with the production of minerals, make it possible to obtain high quality water.

This rock was approved on October 15, 1995 by the Japanese Ministry of Health as having medicinal properties for internal use and in the form of baths.

Ceramic / SGES Tenko Seki
This new type of ceramic made from silica and added Tenko Seki rock, from the Japanese island of Kyushu. This mineral, discovered in 1978, has the property of emitting far infrared in the frequency band of 4 to 14 microns. Contact between water and this mineral leads to the formation of short-lived negative hydrogen ions that act as antioxidants in the body when absorbed. Tenko Seiki rock is also made up of many trace minerals that are released into the water (vanadium, rubidium, zirconium, titanium, magnesium oxide (MgO), aluminum oxide (Al2O3), potassium oxide (K2O), silicon (SiO2) as well as rare earths such as erbium, lanthanum, and lutetium.

The two Japanese volcanic rocks (Bakuhan and Tachyo) are rare igneous rocks that form during the solidification of lava that erupts from a depth of 30,000 meters at a temperature between 1100°C and 2200°C. This gives them the specific qualities mentioned above.

Effectiveness proven by the Hippocrates Institute

The very first reason leading to the importation of this filter by Biovie is the fact that this filtration system was adopted by the Hippocrates Health Institute (USA) in 2001. The Institute abandoned its filtration system and water improvement system installed for more than 20 years for the benefit of this system which treats all the water used by the centre, both for drinking water, for the pools and for external care.

Knowing the scientific rigor of the Hippocrates Institute and their constant search since 1956 for the best non-invasive devices and techniques for human health, the adoption of this system by the Institute (which conducted a specific clinical study on the use of filtered water), was a compelling point for import.

Masaru Emoto's crystals

The first reference comes from a global analysis method, close to sensitive crystallization, which is the analysis of frozen water crystals, the fruit of the work of Masaru Emoto. Polluted waters on a physical or subtle level present chaotic images, while living, energized waters present beautiful crystals.

The blurred areas are due to the fact that the crystals develop in three dimensions at their melting point (transition from the frozen state to the liquid state) and that the microscope can only restore two dimensions, the third being visible by making vary the depth of field. The video report "Les messages de l'eau" makes it possible to witness the formation of such crystals in live.

Redox potential, PH and chlorine

Analysis result from the Water Institute for Life and Natural Science Co.,Ltd.

This analysis shows that the passage of water through the Naturalizer filter increases its PH by 0.49 units and decreases its redox potential by 357 Mv, as the water becomes ionized. Chlorine is completely neutralized.


Ionized water acts as an antioxidant capable of releasing a large amount of electrons, which can bind to free radicals. If there are no antioxidants available, the oxidants present in the body will look for the missing electrons anywhere, this explains in particular that the cell membranes are frequently damaged. Ionized water has a high reduction potential, so it can give up a large number of electrons and thus neutralize free radicals.

On a 2004 analysis by the National Non Additive Foods Association, the redox potential drops from 517 mV to 146 mV.


Our urban Western way of life is generally acidifying: stress, cooked processed food, all forms of pollution are sources of acidification. The blood must be maintained at a constant pH of 7.35 - 7.4. The body has great buffering capacities, the bicarbonates. But this stock is quickly "stolen" in the event of a massive influx of acids. The body must then draw on its ultimate reserves. To neutralize acidity, it draws active minerals from bones, cartilage, hair and teeth. The ionized water buffer allows our body to fight against acidosis.


The health disadvantages of chlorine are relatively well documented. You will find information among others here on Joseph Orzagh's website.

Surface tension

The lower the surface tension of water, the greater its ability to easily penetrate cells and transport nutrients. To obtain their nutrients, cells must be in intimate contact with water. The surface membrane of cells consists mainly of phospholipid molecules. As water and lipids do not mix, when the surface tension of water is too high, the nutrients remain in suspension outside the cells and the cells eliminate their waste with difficulty.

The Naturalizer filter is used at an industrial level in Japan, in particular by the NEC company which uses the solubilization properties of this water for various industrial applications.

This company conducted a study which showed that the water in the Naturalizer had 2.2 times more capacity than tap water to dissolve edible oil (mixed at 2% with water) stirred with some water.

The Naturalizer is distributed in Europe by Biovie, which is the only intermediary between the Japanese manufacturer and the end-customer. This makes it possible to offer this product at a fair price, without making the customer dependent on the purchase of cartridges: the Naturalizer incorporates an exclusive weekly back-cleaning system which gives the device a considerable lifespan.


The concept of the Naturalizer Kirameki filter was developed in 1980 in Japan by the Crystalwater company, which was particularly inspired by major discoveries on the properties of various volcanic rocks in the archipelago. At that time, Harusuke Hairu Nato, Olympic swimming coach and renowned physiologist, sought to provide the best drinking water to his athletes. He is also interested in the vitality of certain populations such as the Hunza, and his research led him in 1984 to develop a water filter made exclusively of natural materials to rid the water of the undesirable substances it conveys, also improving substantially its quality through various processes described below.

The Naturalizer has been the subject of scientific and medical studies in Japan and then in the United States: this is how the Japanese Ministry of Health concluded that regular consumption of water filtered by the Naturalizer filter reduced the harmful effects tap water and provided water whose properties are beneficial to health both internally and externally.

The filter now equips 3 major clinics in Japan in its large-capacity "community" version (see addresses below) and it is even reimbursed by certain Japanese health insurance companies when prescribed by a doctor.

The Naturalizer was introduced in the United States in 2000 under the trade name of Wellness where it was initially offered in its original "long life" version (200,000 liters of filtration capacity). It was then marketed for a few years in a much less interesting new version, without retro-cleaning, which requires frequent renewal of materials.

Origin of the Naturalizer's rocks

1: The repolished sand comes from the Miyazaki area

2: The activated charcoal comes from the Osaka area

3: The volcanic rocks come from the Hokuriku area

4: The magnetite comes from the Kanagawa area

Regarding the Fukhushima disaster, none of the components of the filter come from this area in Japan. The filter components were extracted from the basement well before the disaster and are stored in a warehouse.

A large number of Japanese have also bought this filter following the disaster to filter their drinking water, because the filter also has the ability to retain particles of radioactive isotopes.

Adaptation to your faucet

The filter comes with 6 adapters for installation on a faucet:

  • · 2 male thread kitchen faucet adapters
  • · 2 female thread kitchen faucet adapters
  • · 2 threadless kitchen tap adapters

Caution: If your kitchen faucet consists of a mobile and retractable spray, you will need to install a conventional faucet to be able to connect the Naturalizer.

In case of serious doubt, it is possible to send you only the fittings for verification, without the filter.

Utilisation au quotidien

Une fois le filtre posé, vous pouvez utiliser votre robinet de cuisine indifféremment avec de l'eau filtrée ou de l'eau du réseau en actionnant la manette de sélection.

Il est recommandé de nettoyer votre filtre une fois par semaine pendant environ 3 minutes en faisant couler de l'eau chaude (50 à 60 °C maximum) en position "nettoyage" (l'eau va passer à l'envers en remontant de la base du filtre vers le haut).

En fonctionnement quotidien, le sélecteur (vissé sur votre robinet de cuisine) et vous permet de choisir entre quatre fonctions :

Daily use

Once the filter has been fitted, you can use your kitchen faucet with either filtered water or mains water by operating the selection lever.

It is recommended to clean your filter once a week for about 3 minutes by running hot water (50 to 60°C maximum) in the "cleaning" position (the water will pass upside down coming up from the base of the filter upwards).

In daily operation, the selector (screwed onto your kitchen faucet) enables you to choose between four functions:

1. Back-cleaning

2. Normal tap water (classic jet)

3. Normal tap water ("shower" type jet)

4. Filtered water (dense stream)

You can easily switch from one function to another. This faucet is the only wearing part, and it is possible to buy a new one on our shop.
